Battleship (Solution)

by Davids Farhi and Benjamin

This game is exactly what it appears - you are playing battleship. Except instead of 'Hit' and 'Miss,' you report things according to some rules:

R1: Hits must contain an H
E2: Misses must not contain an "H."
D3: If the space is rectilinearly adjacent to, or on, a ship, it must contain the first letter of that ship's name (Aircraftcarrier, Battleship, Destroyer, Submarine, Patrolboat)
H4: If there are no ships in the space's column at all, the answer must start with the column's letter.
E5: If there are no ships in the space's row, the answer's length must be equal to the row number.
R6: If the Battleship is pointing at the space, its vowels must be in alphabetical order.
R7: If the AIRCRAFT CARRIER is pointing at the space, it must contain a double letter.
I8: If the SUBMARINE points to it, it must have all distinct letters.
N9: If the DESTROYER points to it, the second and second-to-last letters must be equal.
G10: If the PATROL BOAT points to it, it must have an even number of each vowel.
